Pictures of a Coronal Mass Ejection?

tmaromine · 08-20-2008

I have pictures from July '07 that I just looked at, and I wonder if I was able to catch a CME from Earth with a normal digital camera?

I have three pictures, so I wouldn't imagine it a defect or debris on the lens or something like that.

IMHO:
It would appears the illumination of the object you are calling a Coronal Mass Ejection is coming from the sun,
I think you just got some smoke in your picture.

Besides the size of the object you are calling a Coronal Mass Ejection is the size of the sun, and I don’t think that they are that large.

Guess it could've been smoke, especially since it is as large as the sun. Didn't pay attention to that...

DougF · 08-20-2008

Just trying to be objective.

Couldn't be science without it.

As the picture on this wiki page shows, CMEs can be as large as the sun. In fact, they continue propagating outward and can cause ion storms in Earth's atmosphere.

However, the main reason I believe this is a cloud rather than a CME is because CMEs can only be captured by standard photo equipment during eclipses. As the picture shows, they can also be captured with UV photography without an eclipse.

I say cloud too.

Spectacular photograph though.

I checked SOHO, but they are in Bakeout* right now so I can't confirm or deny any CME's when you took the image.

*What's a CCD bakeout, anyway?

tmaromine · 08-20-2008

Wish I'd paid some attention that day. Oh well.

And I have hundreds more photos like that (and at better quality; those'er zoomed it seems). Just never got them onto the netz. I should get my good nature photos out for the world.

DougF · 08-20-2008

yes, I've said that before, well here is a strange one for you,
and I'll try to stay on topic from now on.

Amazing striped icebergs
Icebergs in the Antarctic area sometimes have stripes, formed by layers of snow that react to different conditions.
Blue stripes are often created when a crevice in the ice sheet fills up with meltwater and freezes so quickly that
no bubbles form.
When an iceberg falls into the sea, a layer of salty seawater can freeze to the underside. If this is rich in algae, it
can form a green stripe. Brown, black and yellow lines are caused by sediment, picked up when the ice sheet
grinds downhill towards the sea.

Icebergs are a little off topic from the sun, or are we into interesting nature pictures now? Either way, that iceberg is interesting. Never heard or seen of that before. It'd've been nice if the photographer had more than a cellphone though...
